Kai's verdictA-tier. Best for teaching a kid to code in 2026.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for teachers. If you teach K-12, start here this week.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
